Budget 12A SP build

[t_g_farrell]

Not much new to report yet. I've been cleaning rotors, housings and irons.
I think I can reuse the dented rotor. It seems fine other than the dent near
the combustion indent. I was able to get all the side seals out of it and the
rest of the rotor appears fine.

I think most of the A engine can be reused except for the rear iron. I think
the rear iron from the B engine is actually in better shape. There is some
mild stepping at the spark plug side but I'm thinking it will be in spec. I have
yet to get some feeler guages for thousandths of an inch. The A engine irons
are all Ys whereas the B engine irons are Rs. Is it ok to use the R iron with
the other Y irons? Now that I cleaned em up I don't see huge differences
between them.

The stationary bearings don't look new like the rotor bearings. Some copper
showing on the lower part of the bearing and at the seams. They don't look
that much different from the ones in the B engine, which had a lot of hard
miles on it. Thinking I may need to change those out.

I pulled the e-shaft oil jets and they had disintegrated o-rings in them. I
think I can safely say those were never replaced.

I'm thinking about doing the oil pressure mod to the regulator where you
mash down the tip to get it to about 90 psi and shim the front one. This
will be a SP with spirited driving and some track days. Is it worth it? I don't
think I need to do anything with the e-shaft jets other than new o-rings.
I can't see having extra pressure being a problem as long as my lines and
cooler can handle it.
